nmap扫描结果有哪些 如何使用nmap扫描一个网段的主机

nmap扫描结果有哪些 如何使用nmap扫描一个网段的主机?很多人不了解,今天趣百科为大家带来相关内容,下面小编为大家整理介绍。

1. Nmap系统识别

(1)识别操作系统

nmap -O

确定目标主机192.168.33.152的操作系统类型。按如下方式执行命令:

从2021年8月2日15:22 CST开始Nmap 7.70(https://pic.qubaike.com/pic/2023-03-31/mnoelzzyb5cs://pic.qubaike.com/pic/2023-03-31/5iq54audkg1

主机启动(0.00036秒延迟)。

以上输出信息就是Nmap向数据库提交的指纹信息,这些指纹信息是自动生成的,并且标识了目标系统的操作系统。

Nmap done: 256 IP addresses (6 hosts up) scanned in 7.64 seconds

从以上输出信息可以看到,如果探测到目标主机上存在开放的端口,则推测出了其操作系统类型;如果目标主机上不存在开放的端口,则无法推测其操作系统类型。

(3)推测操作系统

Nmap无法确定所探测的操作系统时,会尽可能地提供最相近的匹配。为了对目标系统推测得更准确,可以使用--osscan-guess或--fuzzy选项来实现。语法格式如下:

nmap -O --osscan-guess;--fuzzy

其中,--osscan-guess;--fuzzy选项用于推测操作系统检测结果,将以百分比的方式给出对操作系统信息的猜测。当Nmap无法确定所检测的操作系统时,会尽可能地提供最相近的匹配。Nmap默认进行这种匹配,使用任意一个选项将使得Nmap的推测更加有效。

推测目标主机www.163.com的操作系统类型。执行命令如下:

root@daxueba:~# nmap -O --osscan-guess www.163.com

Nmap scan report for www.163.com (124.163.204.105)

表1 各个操作系统的初始TTL值

使用Ping测试目标主机(192.168.33.152)的操作系统类型(该目标主机的操作系统类型为Linux)。执行命令如下:

root@daxueba:~# ping 192.168.33.152

64 bytes from 192.168.33.152: icmp_seq=1 ttl=64 time=0.242 ms

64 bytes from 192.168.33.152: icmp_seq=3 ttl=64 time=0.431 ms

PING 192.168.33.229 (192.168.33.229) 56(84) bytes of data.

64 bytes from 192.168.33.229: icmp_seq=2 ttl=128 time=1.01 ms

64 bytes from 192.168.33.229: icmp_seq=4 ttl=128 time=1.52 ms

从输出的信息可以看到,该响应包中的TTL值为128。由此可以说明,这是一个Windows操作系统。

从以上输出的信息中可以看到,执行结果出错了(HP JetDirect ROM G.07.02 EEPROM G.07.17)。

在Kali Linux的新版本中,xProbe2工具运行后,测试的结果中操作系统类型显示为乱码。具体如下:

<+> Primary guess:

<+> Other guesses:

<+> Host 192.168.1.8 Running OS: ????U (Guess probability: 100%)

<+> Host 192.168.1.8 Running OS: ?????U (Guess probability: 100%)

4. p0f系统识别

p0f是一款用于识别远程操作系统的工具,该工具与前面介绍的其他工具不同,它是一个完全被动地识别操作系统指纹信息的工具,不会直接作用于目标系统。当启动该工具后,即可监听网络中的所有数据包。通过分析监听到的数据包,即可找出与系统相关的信息。下面介绍使用p0f工具来实施操作系统指纹识别的方法。

使用p0f工具对目标主机实施系统识别。执行命令如下:

1)启动p0f工具。执行命令如下:

root@daxueba:~# p0f

<+> Closed 1 file descriptor.

<+> Intercepting traffic on default interface 'eth0'.

<+> Entered main event loop.

从以上输出信息中可以看到,p0f工具仅显示了几行信息,无法捕获到其他信息。但是,p0f会一直处于监听状态。

2)此时,当有其他主机在网络中产生数据流量的话,将会被p0f工具监听到。例如,在另一台主机上通过浏览器访问一个站点,然后返回到p0f所在的终端,将看到如下信息:

.-< 192.168.1.4/38934 -> 65.200.22.161/80 (https://pic.qubaike.com/pic/2023-03-31/mnoelzzyb5c request) >- #https://pic.qubaike.com/pic/2023-03-31/c5teypwar5u

| app = Safari 5.1-6 #应用

| params = dishonest #程序

----

| server = 65.200.22.161/80 #服务器

| raw_freq = 1048.46 Hz #频率

.-< 192.168.1.4/38934 -> 65.200.22.161/80 (https://pic.qubaike.com/pic/2023-03-31/mnoelzzyb5c response) >-

| raw_mtu = 1500

.-< 192.168.1.4/32856 -> 52.27.184.151/443 (syn) >-

| os = Linux 3.11 and newer

| params = none

----

以上输出的信息,就是执行监听到客户端访问的数据信息。从以上输出的信息可以看到,探测到客户端的操作系统类型为Linux 3.11或更新的内核版本。
